I am building a model in ArcGIS pro. I am trying to set range for months value list (January, February, March, April, September, October, November, December) whereby a user can select from , for instance, from January - March, or September - December. I have done it and it is working but the down side of it is, it selects alphabetically i.e if I select from April it will select all values of month from A-S, but if I select from January to April, it returns null because numerically J does not come before A.. how can i solve this to make it select January to April or September to December to return a value. Like how can I set the value to select flexibly not minding the alphabetical order. Thanks
